Application filed April 16,

- in connection'with the accompanying'drawtion,-some of the parts being broken away;

ings, is a specification, likecharacters on the drawings representing like parts. V v This invention relates to ffeeler- Inechanisms for looms, and more particularly to that type of such mechanisms now, commonly known as penetrating ieeler mechanisms.

In the penetrating type offeeler .mecha nism, it is the usual practice to, provide an impinging and a penetrating feeler which enter the shuttle on each detecting beat and feel for the filling. ply of filling is present on a detecting beat,- the penetrating feeler enters the filling mass and then the impinging feeler engages the surface of the filling mass andthe two are moved frontwardly during the remaining portion of the lay; advance,

One of the objects ofthe present invention is to improve ieeler mechanisms ofthis type, and mo-reparticularly withrespect t0 the connection between the penetrating-feeler and the actuator with whlch tcooper-ates ,1n eiiectlngreplenlshment of filling.

It is desirablethat the'filling' engaging end of the penetrating feeler have s 'iflicient freedom of movement to permit .it to move frontward blow of the advancing laterally slightly andto turn slightly about its longitudinal axes. Such freedom of move ment permits the penetrating feeler more readily to enter bet-ween adjacent coils of filling upon the filling carrier. In the present' construction the relatively short bearing 21 through which the penetrating feeler 22 loosely extends in connection with the ball 26 and cooperating socket at the front end of the penetrating feeler, support the feeler with the desired freedom of movement, while the feeler is maintained positively connected to the actuator 16. The penetrating feeler is shown as supported so that the bent intermediate portion of the feeler is permitted a limited rocking movement relative to the supports for the ends of the feeler.

are moved .frontwardly together against the The shuttle 29 carries the usual filling carrier or bobbin 30, and its front wall is slotted at 31 for the entrance of the impinging and penetrating feelers on a detecting beat.

When a working'supply of filling is present in the shuttle on a detecting beat, the normally projecting rear end of the penetrating feeler first enters the mass of filling or sinks into it between the coils thereof, and then the surface of the filling meets the impinging feeler and the feeler members normal'action of the spring 11; When, however, the filling is substantially exhausted on a detecting beat, the penetrating feeler 22 will be engaged by the more dense surface of the fillingcarrier or bobbin and forced frontwardly relative to the impinging feeler, thereby moving theactuator into operative position, substantially as indicated inFig. 2, by depressing the front end portion of the actuator into a position for engagement with i the end of the .transmitter 8 as the two'feelers and slide 9 are movedfrontwardly, to

thereby eflect replenishment of filling.

Since the front end of the penetrating feeler is in positive connection with the actuator, manipulation of the adjusting screw .25 1n elther direction, efiects corresponding adjustment of the end of the penetrating feeler withrespect to the face of the impinging feeler, and a delicate relation of the end of the penetrating feeler and the impinging face of the impinging feeler is readily effected. When the screw 25 has been adjusted, it may be located in position by a lock nut 32.

What is claimed is:

'1. In a feeler mechanism for looms, the combination of an impinging feeler, a penetrating feeler which passes loosely through the impinging feeler, an actuator, a ball and enclosing socket connection between the impinging feeler and actuator which positively connectsv the two and prevents disengage ment of the feeler from the actuator means engaging the ball and positively holding it in the socket. I

2. In a feeler mechanism for looms, the

combination of an impinging feeler, a penetrating feeler which passes loosely through the impinging feeler, an actuator, a ball formed on one end of the penetrating feeler,

an adjusting screw formed with a socket the edge walls of which enclose the ball and form ,a' positive connection between and prevent disengagement of the penetrating feeler and actuator. j

In a feeler mechanism for 1001115, the combination of a. penetrating feeler, an impinging feeler having a bearing for loosely supporting the rear end of the penetrating feeler and adap'ted to permit a limited rocking movement of the forward end of the penetrating feeler relative to said-bearing as a pivot, an actuator, a ball and enclosing socket connection between the impinging feeler and actuator which positively connects the two and prevents disengagement of the feeler from the actuator.

4. In a feeler mechanism for looms, the

combination of a penetrating fee1er,an impinging feeler having a bearing for loosely supporting the rear end of the penetrating feeler, an actuator, a ball formed at the forward end of the penetrating feeler, means upon the actuator having a socket receiving said ball and having edge portions for positively holding the ball within the socket and forming a positive connection for preventing disengagement of the feeler and actuator, I

said bearing and socket being constructed and arranged to support the penetrating feeler to permit a limited rocking movement of the intermediate portion of the feeler.

'In testimony whereof, I have signed my name to this specification. I
